Cowboy Bebop is visually stunning, with gorgeous CGI; it also has stark bright colors, pitch darkness, and drastic contrasts that evoke film noir. The character design is also mainly straight out of 1940 by way of 1971.

Neon Genesis Evangelion and End of Evangelion are likewise beautifully animated (especially note all the reflections on the lenses of Gendo's eyeglasses, and remember that NGE was made in 1995--years before the tools to do that as CGI were common and cost-effective), and the giant mecha fight scenes are, particularly in EoE, absolutely breathtaking.

Wolf's Rain is also visually attractive, with dull, drab, washed-out colors that evoke a sense that the world is dying.
